A property manager responsible for a portfolio of mid-rise commercial buildings across inner Melbourne opened a letter in 2018 that changed how she thought about every facade she managed. One of her buildings, a nine-storey office block in the inner north, had been identified as carrying aluminium composite panel cladding with a polyethylene core. What had looked for a decade like an ordinary architectural finish was now a documented fire-safety concern, subject to assessment, potential rectification, and a compliance obligation she had never previously had to consider. She was not alone. In the years since the Lacrosse tower fire in Docklands and the Grenfell Tower tragedy in London, combustible cladding has moved from an obscure technical matter to one of the most consequential issues in Australian building management, and a competent cladding inspection has become a defining responsibility for facilities managers across Melbourne.

Cladding is the external skin of a building, and on a large portion of Melbourne’s building stock constructed between the late 1990s and the mid 2010s, that skin may contain materials that behave dangerously in a fire. Understanding what a cladding inspection involves, when it is required, who is qualified to perform it, and how it connects to a building’s broader maintenance and safety programme is now essential knowledge for anyone managing commercial, institutional or multi-residential property in Victoria. This guide sets out the regulatory background, the technical realities of combustible cladding, the inspection methodology, and the procurement considerations that building professionals need to act on.

Why Combustible Cladding Became a Compliance Priority

For most of the period in which it was installed, combustible cladding was not treated as a hazard. Aluminium composite panels, which sandwich a polymer core between two thin aluminium sheets, were prized for being lightweight, weather resistant and easy to work into clean modern facades. Expanded polystyrene render systems offered thermal performance and a smooth finish at low cost. Both were installed extensively across Melbourne, and for years no one subjected them to the scrutiny that a cladding inspection now applies.

The turning point came with fire. The 2014 Lacrosse building fire in Docklands demonstrated how rapidly flame could travel up a facade clad in aluminium composite panels with a polyethylene core. A discarded cigarette on a balcony escalated within minutes into a fire that climbed thirteen storeys. Three years later, the Grenfell Tower fire in London killed seventy-two people and burned in a way that made the mechanism impossible to ignore. The polymer core of the panels, once ignited, behaved like a concentrated fuel source distributed across the entire external surface of the building. These events forced a reassessment of a material that had been installed on thousands of buildings, and they are the reason cladding inspection is now a standing item in responsible facilities management rather than an occasional afterthought.

In Victoria, the response was structured and sustained. The state government established the Victorian Cladding Taskforce to investigate the extent of the problem, and subsequently created a dedicated programme to audit and rectify buildings carrying high-risk cladding. Thousands of Melbourne buildings were assessed. For facilities managers, the practical consequence is that combustible cladding is no longer a latent issue that can be left undisturbed. It is an active compliance obligation, and a documented cladding inspection is the mechanism by which a building owner establishes what they are dealing with and demonstrates that they are managing it responsibly.

The Victorian Regulatory Framework for Cladding

Facilities managers cannot approach cladding inspection in isolation from the regulatory framework, because the obligation to identify and manage combustible cladding is enforced through several intersecting instruments. Understanding how they fit together is essential to defensible building management and to producing compliance documentation that will withstand scrutiny.

The National Construction Code sets the performance requirements governing the fire behaviour of external walls, including the combustibility of cladding materials on buildings of certain heights and classifications. Where cladding does not meet these requirements, the building carries a non-compliance that must be assessed and managed. The Building Act and the Building Regulations provide the enforcement architecture in Victoria, including the powers of the building regulator to require rectification and the framework for building orders and notices. Since 1 July 2025, the Building and Plumbing Commission Victoria has assumed the building regulatory functions previously administered by the Victorian Building Authority, and facilities managers should ensure their cladding inspection reports and rectification correspondence reference the current body.

The essential safety measures regime is directly relevant. Under the Building Regulations, a building owner must maintain nominated safety measures and produce an annual essential safety measures report. Where cladding rectification has introduced or modified fire-safety systems, or where a building carries a fire-engineered solution to manage combustible cladding risk pending rectification, those measures form part of the essential safety measures obligation. A cladding inspection feeds directly into this documentation, establishing the baseline condition against which ongoing safety measures are maintained. Overlaying all of this is the Occupational Health and Safety Act 2004 and the Occupational Health and Safety Regulations 2017, which impose a duty on those who manage or control a workplace to ensure, so far as is reasonably practicable, that it is safe. A building with unassessed combustible cladding is a workplace whose fire risk has not been characterised, and the reasonable-practicability standard effectively requires that a facilities manager know the cladding status of the buildings they control. That knowledge begins with a cladding inspection.

Understanding What a Cladding Inspection Is Looking For

A competent cladding inspection is a structured investigation into the materials that make up a building’s external envelope and the way those materials behave in a fire. It is not a visual glance at a facade, because the critical characteristics of cladding are frequently invisible from the outside. Two panels that look identical can differ entirely in their core composition and therefore in their fire performance. Understanding what the inspection is actually determining allows a facilities manager to interpret a report and act on it.

Identifying the Cladding Type and Core Composition

The central question in most cases is the composition of the material behind the visible surface. Aluminium composite panels are the highest-profile concern, and the inspection must determine whether a panel carries a full polyethylene core, a fire-retardant core, or a mineral core, because these behave very differently when exposed to flame. This often cannot be established by looking. It may require examination of panel edges, review of original construction and product documentation, and in some cases sampling and laboratory analysis. A cladding inspection that stops at surface appearance has not answered the question that matters.

Assessing Extent, Location and Fire Pathways

Beyond identifying the material, the inspection assesses how much of it is present, where it sits on the building, and how it relates to fire pathways. Combustible cladding around windows, on balconies, near building services penetrations, or forming a continuous vertical run up a facade presents a different risk profile from an isolated panel at low level. The inspection maps the distribution of the cladding and considers how a fire could spread across and up the facade, which is the information a fire engineer needs to characterise the building’s risk and design any interim or permanent response.

Evaluating Condition, Fixings and Weather Integrity

A cladding inspection also examines the physical condition of the facade system. Panels can loosen, fixings can corrode, and sealed junctions can fail, particularly in Melbourne’s coastal and marine-influenced suburbs where salt air accelerates deterioration of metal components. Compromised weather integrity is a maintenance problem in its own right, and it can also alter fire behaviour where cavities and gaps open up behind the cladding. This is where the assessment overlaps with general facade condition evaluation and where the involvement of a contractor experienced in commercial facade repairs adds value beyond a narrow combustibility check.

The Role of Access in a Thorough Cladding Inspection

Access is the practical constraint that determines whether a cladding inspection is genuinely thorough or merely partial. The panels that matter most are frequently the ones that cannot be reached from the ground or from inside the building. Upper-storey facades, balcony soffits, plant-room screens and the concealed edges where core composition can be examined all sit at height, often on the external face of the building where no internal access exists.

This is where rope access and height safety capability become decisive. IRATA-certified rope access technicians can position themselves precisely against any point on a facade, examine panel edges and junctions at close range, take samples where required, and document the cladding across the full height of the building without the cost and disruption of scaffolding or a building maintenance unit deployment. Delivering this work under a documented safe work method statement and full height safety controls means the inspection reaches the surfaces that determine the building’s actual risk, rather than the limited subset visible from the footpath. The regulatory obligations that govern working at height on a Melbourne facade are set out in full in our guide to height safety compliance for Melbourne commercial buildings, and they apply to a cladding inspection just as they apply to any other access-intensive facade task.

The access advantage compounds over time. A contractor already mobilised on the facade for high-rise window cleaning is positioned at exactly the surfaces a cladding inspection must reach, which means condition monitoring of the facade can be folded into a recurring maintenance programme rather than commissioned as a standalone exercise every time. This is one of the practical arguments for engaging a provider whose capability spans window cleaning, facade assessment and height safety under a single operational umbrella. The inspection becomes a repeatable part of the maintenance rhythm rather than a costly one-off.

Integrating Cladding Inspection with Facade Maintenance

The most effective approach treats cladding inspection not as an isolated fire-safety task but as one element of a coordinated facade management programme. Cladding shares its environment, its access requirements and often its deterioration drivers with the glazing, sealants and facade elements around it, and inspecting it in coordination with related works delivers both better information and lower cost.

Water ingress illustrates the connection. A failed sealant junction or a loosened panel that admits water is a maintenance defect, but it can also affect how a facade system performs in a fire and how quickly concealed components deteriorate. Detecting these issues early, during routine facade works, prevents them compounding. This is the same logic that underpins our detailed guidance on facade inspections during window cleaning, where combining access-intensive tasks turns every facade visit into an opportunity to monitor condition. A combustibility check sits naturally within that framework as the fire-safety dimension of a whole-of-facade assessment.

Coordinating cladding work with planned building maintenance also reduces the number of separate access mobilisations a building requires. Where rectification is required, addressing it while a contractor is already on the facade is faster and more cost-effective than sequencing a fresh procurement and a new access setup. For facilities managers weighing this against the broader inspection calendar, our guidance on annual safety inspections for high-access buildings sets out how facade and cladding checks fit into a coordinated scheduling framework rather than being commissioned in isolation.

When a Cladding Inspection Is Required

There is no single interval that governs every inspection, because the trigger for one depends on the building’s history, its cladding status, and where it sits in the regulatory process. Facilities managers can, however, work from a clear set of circumstances that warrant inspection.

Any building that has not yet been assessed for combustible cladding, and which was constructed or refurbished during the period when the relevant materials were commonly installed, warrants a cladding inspection to establish its status. A building already identified as carrying high-risk cladding requires ongoing attention through the rectification process, including confirmation that interim safety measures remain effective and that the facade has not deteriorated in ways that change its risk. A building that has completed rectification still benefits from periodic facade condition monitoring to confirm that the new system continues to perform and that fixings and junctions remain sound.

Certain events should also prompt inspection. A change of building classification or use that alters the applicable fire-safety requirements is a trigger. Physical damage to the facade from a storm, an impact or a minor fire event warrants assessment of whether cladding integrity has been compromised. And the sale or refinancing of a building frequently requires current documentation of cladding status, since combustible cladding materially affects a building’s value, insurability and marketability. In each of these circumstances, a documented cladding inspection is the instrument that establishes the facts.

The Insurance and Financial Dimension of Cladding Status

For facilities managers, the consequences of cladding status extend well beyond fire safety into the financial and contractual health of the building, and this is a dimension that a cladding inspection increasingly serves. Since combustible cladding became a recognised risk, insurers have treated it as a material factor in underwriting. Buildings with unassessed or unrectified high-risk cladding have faced higher premiums, reduced cover, exclusions, and in some cases difficulty securing insurance at all. An insurer asked to cover a building will want to know its cladding status, and a documented assessment is frequently the evidence that answers the question. Without it, a facilities manager is negotiating from a position of uncertainty that the insurer will price accordingly.

The same dynamic applies to transactions. When a building is sold or refinanced, cladding status is now a standard element of due diligence. A purchaser or a lender will want current documentation establishing what cladding the building carries and what, if any, remediation obligation attaches to it. A building presented to the market with an unresolved cladding question invites discounting, extended negotiation, or a collapsed transaction, whereas one supported by a clear inspection record and a defined management pathway is a far more straightforward proposition. For owners corporations in particular, where the cost of rectification is ultimately borne by lot owners, transparent documentation of cladding status is both a governance obligation and a protection against future dispute.

Budget planning is the third financial consideration. Cladding rectification can be a substantial expense, and it is one that facilities managers and owners corporations are better placed to plan for when they understand their position early. An inspection that characterises the cladding, its extent and its risk allows a building to sequence any required works, apply for available support where eligible, and avoid the far higher cost of an emergency response forced by an incident or a regulatory order. Treating the assessment as a planning tool rather than a reluctant compliance cost is the posture that serves a building’s finances best over the long term.

The value of a cladding inspection depends entirely on the competence of the provider, and this is where facilities managers exercise the most consequential judgement. A superficial inspection that misidentifies a polyethylene-cored panel as safe, or that examines only the accessible portion of a facade, produces false assurance and a compliance record that will not survive scrutiny after an incident. Selecting the right provider is a risk-management decision in its own right.

The first consideration is the technical scope of the assessment. Determining the fire performance of cladding often requires more than visual identification, and a competent provider will be clear about when core composition must be confirmed through documentation review or sampling rather than assumed from appearance. Where fire-engineering judgement is required to characterise risk, that expertise must be part of the process. The second consideration is access capability. A provider that can only inspect what is reachable from the ground or from inside the building will miss the upper-facade panels and concealed junctions that determine the building’s actual risk. IRATA-certified rope access, delivered under proper height safety controls and a documented safe work method statement, is what allows a genuinely complete examination of the full facade.

The third consideration is documentation and integration. The provider should deliver a written report with photographic evidence, a clear record of the cladding types identified and their locations, the methodology and standards applied, and recommendations a facilities manager can act on and defend. Appropriate public liability insurance and current high-risk work licensing for the access methods employed are non-negotiable. A provider whose capability spans window cleaning, facade repairs, glazing assessment and height safety brings the further advantage of being able to move from inspection to remediation without a fresh mobilisation, and of building familiarity with the building over successive visits so that change is detected between formal inspections rather than missed. This continuity is one of the strongest arguments for consolidating cladding inspection within an ongoing facade maintenance relationship rather than treating it as a discrete transaction.

Turning Cladding Findings into a Managed Response

A cladding inspection that identifies a concern but does not connect to a clear response pathway leaves a facilities manager exposed. The report should characterise the cladding, locate it, and set out the recommended next steps, whether that is further investigation, referral to a fire engineer for a risk assessment, interim safety measures, or a rectification pathway. This allows the building owner to move deliberately from knowledge to action rather than sitting on an unresolved finding.

Where rectification is required, it is a significant undertaking that typically involves fire engineers, builders and the building regulator, and it sits beyond the scope of a facade contractor alone. What a specialist facade and access contractor contributes is the accurate baseline the whole process depends on, the safe access that inspection and remediation works require, and the ongoing condition monitoring that confirms interim measures remain effective while a permanent solution is progressed. Documenting each stage completes the compliance loop and feeds the essential safety measures report, demonstrating that the building owner has not only identified the risk but is actively managing it.

For Melbourne facilities managers, property managers and owners corporations, a disciplined approach to cladding inspection is now a defining feature of responsible building management. It characterises a fire risk that was invisible for decades, it satisfies a web of Victorian regulatory obligations, and it protects occupants, asset value and insurability. Engaging a specialist contractor with genuine facade expertise, IRATA-certified rope access capability, and integrated window cleaning, facade and building maintenance services means a single relationship can cover inspection, monitoring and the access that rectification demands across the life of the building.
